The difference is: If you lose your smartcard, it's pretty straight forward for your employer to verify your identity and issue a new one. How do I do that with WhatsApp? We all know how well these tech giants react if you got permanently locked you out of accounts, no matter whose fault it was. And even if I could get a new key, I would have to explain to all my contacts why my key changed and they would have to re-verify it over a secure channel. It doesn't scale. Now you might say: just keep multiple copies, but there will be cases where people lose all copies, and depending on how much of our digital lives will be tied to these keys, we will need a secure recovery plan for that.
